Claims. 1

'I'h'is invention relates to new and useful improvements in a permanentseparating magnet.

The invention contemplates the construction of a magnet which ischaracterized by a non-magnetic housing for a magnet, a magnet withinsaid housing, and a handle by which the housing may be convenientlycarried around. With this device it is possible to pick up small iron orsteel objects. It is Very useful around factories to p up iron filings,and steel and iron chips.

Still further the invention contemplates several modified forms embodyinsevera1 improved features. One form is proposed in which it is possibleto readily drop the attracted filings or other small articles, whendesired. Another form is proposed in which the strength of the magnetmay be varied.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective View of a permanent separating magnetconstructed in accordance with this invention.

Fig. 2 is an enlarged vertical sectional View taken on the line 2--2 ofFig. 1.

Fig. 3 is a longitudinal sectional View taken on the line 3-3 of Fig. 1.

Fig. 4 is a, perspective View of a permanent separating magnet embodyinganother form of this invention.

Fig. 5 is a longitudinal sectional View taken on the line 5--5 of Fig.4.

Flg. 6 is a transverse sectional View taken on the line 6-6 of Fig. 5.

The permanent separating magnet, in accordance with the form of theinventon illustrated in Figs. l-3 inclusive includes a non-metallichousing O for a magnet ll. A handle |2 is provided by which said housingIO may be carried around. The housing ll i in the nature of a box havinan open bottom. This bottom is closed by a wall I 3. Severa screws |4are engaged through said wall l3 and extend through openings I 5 in backof the magnet I I and engage and hold the handle !2 in position.

The screws |4 have their heads projecting from said wall l3 so that whenthe separating magnet is placed on a fiat surface, such as indicated bythe dot and dash lines l5', it will be slightly spaced therefrom. Thispermits the separating magnet to operate over fiat surfaces and overarticles to be picked up. The magnet II is in the nature of a horseshoemagnet. It extends the entire length of the housing ill. It ha its polesdirected downwards against the bottom Wall I 3.

The shape of the magnet l l and housin n may be square, round or ofother configuration and the magnet may be attached to other devices suchas a sWeepng broom, automobile body, etc.

In Figs. 4-6 another embodiment of the invention has been disclosed.This separating magnet includes a, non-magnetic housing 20 for magnets2! and 22. The housing 20 is provided with a handle 23 by which it maybe conveniently carried about. The housing 20 is in the nature of a boxhaving an open bottom, and a Wall 24 extends across the bottom andprojects slightly from the sides of the housing 20. several screws 25pass through the wall 24 and through openings in the magnets 2| andthreadedly engage bushings 25 located within recesses 27 formed in thebottom of the handle 23. These bushings 26 are urged upwards by coaxialsprings 28 acting against plates 29 mounted in the bottom of the handle23.

There are three of the magnets 2| arranged one adjacent the other withinthe housing 20. They are connected with the housing by fastening screws30. The magnet 22 is of a smaller size than the magnets zl and isslidable between the poles of the magnet 2l. The magnet 22 has shoulders32 spaced slightly above complementary shoulders 33 formed upon thepoles of the magnets 2l. With this arrangement the magnet 22 Will notfall down Very far if the wall 24 is removed, since the shoulders 32 and33 will engage each other and support the magnet 22.

The wall 24 is formed with two roWs of serrations 35 which areengageable With complemen tary serrations 35 formed on the bottom endsof the poles of the magnet 22. When the bottom Wall 24 is held by thescrews 25 the serrations 35 and 36 engage each other, holding the magnet22 from shifting. The heads of the screws 25 project from the bottomface of the Wall 24 to hold same spaced from a flat surface, indicatedby the dot and dash lines 26, However, the bottom wall 24 may bemanually gripped and pulled down wards so that the bolts 25 movedownwards, moving the bushings 26 downwards and compressing the springs28. This frees the magnet 22 which then may be shifted to one end or theother end, or the center of the housing 20, as desired. Moreover,downward motion of the Wall 24 to the 3 position indicated by the dotand dash lines 24' is suificient to move picked up small articles out ofthe strong magnetic field so that the articles are dropped.

The purpose of shifting the magnet 22 is that one end or the other end,or the center of the permanent separating magnet may be thus arranged tohave stronger magnetio power than the remaining portions.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I. claim as new, and desire tosecure by United States Letters Patent is:

1. A permanent separating magnet, comprising a non-magnetic housing'fora magnet, a magnet within said housing, and a handle on said housing,said housing having a removable bottom wall, screws with projectingheads engaged through said bottom wall for holding same in position,said screws extending through the housing and connecting with andholding said handle on the top of said housing.

2. A permanent separating magnet, comprising a non-magnetic housing fora magnet, a magnet within housing, a handle on said housing, and anadditional magnet for extra lifting power slidahly Inounted within aportion of said magnet.

3. A permanent separating magnet, comprising a non-magnetic housing fora magnet, a magnet within said housing, a handle on said housing, and anadditional magnet for extra lifting power slidably mounted within aportion of said magnet, and means for holding said latter-named magnetin selected shiited positions.

4. A permanent separating magnet, comprising a non-magnetic housing fora magnet, a magnet within said housing, a handle on said housing, and anadditional magnet for extra lifting power slidably mounted within aportion of said magnet, and means for holding said latter-named magnetin selected, shifted positions, including a bottom wall for said casing,and resilient means for urging said bottom wall against the ends of saidlast-named magnet for clamping same in position.

5. A permanent separating magnet, comprising a non-magnetic housing fora magnet, a magnet within saidhousing, 'a handle on said housing, andanadditional magnet for extra iifting power slidably mounted within aportion of said magnet, and mean for holding said latter-named magnet inselected shiited positions, including a bottom wall for said casing, andresilient means for urging said bottom wall against theends of saidlast-named magnet for clamping same in position, said bottom Wall beingseparable from the other portions of said housing to cause magneticallyplcked up articles to be dropped.
